Infant Synesthesia / A Developmental Stage

No, synesthesia is not a disease. In fact, several researchers have shown that synesthetes can perform better on certain tests of memory and intelligence. Synesthetes as a group are not mentally ill. They test negative on scales that check for schizophrenia, psychosis, delusions, and other disorders.

What if many or all of the symptoms “assigned” by psychologists to Asperger Disorder are actually the manifestations of Synesthesia? Would it be incorrect to label us developmentally defective when our supposedly pathological behavior is “normal” for our distinct sensory experiences?

Infants Possess Intermingled Senses

Babies are born with their senses linked in synesthesia

by Maria Konnikova, January 1, 2012

What if every visit to the museum was the equivalent of spending time at the philharmonic? For painter Wassily Kandinsky, that was the experience of painting: colors triggered sounds. Now a study from the University of California, San Diego, suggests that we are all born synesthetes like Kandinsky, with senses so joined that stimulating one reliably stimulates another.

The work, published in the August issue of Psychological Science, has become the first experimental confir­mation of the infant-synesthesia hy­pothesis—which has existed, unproved, for almost 20 years.

Researchers presented infantsand adults with images of repeating shapes (either circles or triangles) on a split-color background: one side was red or blue, and the other side was yellow or green. If the infants had shape-color asso­ciations, the scientists hypoth­esized, the shapes would affect their color preferences. For in­stance, some infants might look significantly longer at a green back­ground with circles than at the same green background with triangles. Absent synesthesia, no such dif­ference would be visible.

The study confirmed this hunch. Infants who were two and three months old showed significant shape-color associations. By eight months the preference was no longer pronounced, and in adults it was gone altogether.

The more important implications of this work may lie beyond synesthesia, says lead author Katie Wagner, a psychologist at U.C.S.D. The finding provides insight into how babies learn about the world more generally. “In­fants may perceive the world in a way that’s fundamentally different from adults,” Wagner says. As we age, she adds, we narrow our focus, perhaps gaining an edge in cognitive speed as the sensory symphony quiets down.
